Be it known that I, Ti-iiioDoRE SMITH, a citizen of the United States, residing at Chicago, in the county of Cook and State of lllinois, have invented a certain new and useful Improvement in Telephone Apparatus, of which the following is a specification.

My invention relates to telephone apparatus, and has for its object to provide a new and improved device of this description.

My invention is illustrated in the accompanying drawing, wherein- Figure l shows a device embodying the invention; Fig. 2 is a plan view of the telephone receiver and transmitter; Fig. 3 is a front view thereof as seen in the direction of the arrow (see Fig. l) with parts omitted; Fig. 4 is a sectional view on line 4.-4 of Fig. 3; Fig. 5 is a sectional view showing the spring lift device.

Like letters refer to like parts throughout the several figures.

The telephone apparatus is connected to an adjustable bracket attached to the wall, said bracket comprising an end piece A, and a laterally movable piece B mounted thereon, and to which are connected the projecting pieces C and D which are pivotally connected to a center piece E4 which in turn is rotatably mounted upon the part B. Associated with the pieces C and D is a frictional clamping device E and a spring lift device F. The frictional clamping device consists of two parts E1 and E2. The part E1 is vpreferably fixed to the piece C, and the piece D is pivetally clamped between the arts E2 and E1 by means of a thumb screw i 3 passing therethrough. The spring lift device consists of a spring F1 inclosedin two hollowl tubes F2, F3 overlapping, as shown in Fig. 5.. These tubes are provided with engaging-parts which engage the ends of the springso that the tension of the spring may be varied by moving them toward or from each other. The tube F2 is Xed to the piece D, and the tube F3 has a screw threaded connection with a sleeve F4 which engages the 'clamping device E and is held against rotation by the projection F5. A lock nut F6 ward the sleeve F8 and causes it to move 'toward the sleeve F2, and thus compress the spring. When the device is released it will stay in this position, but by applying a slight upward pressure to it it can be moved up,l the spring actin toassist in this movement. The pieces C an D are pivotally connected to a connecting piece G to which is ivotally connected a connecting link G1. ivotally connected to this link is a cylindrical part H `pixovided at its end with a curved neck H1 to which is rigidly connected the telephone transmitter H1. The electric conductors for the telephone pass through the pieces B and C and G and G1 and into the cylinder H wherethe proper connections are made.` Associated with the cylinder H is a pivoted arm I pivotedat 11 and provided with a switch actuating piece I2 which pro-- jects into said cylinder. A signaling switch H3 is mounted upon said cylinder which is provided with a removable side piece H4, said signaling device beingl located upon said removable side piece. This side piece is held in position hy the screws H5. Attached to the arm I is the receiver hook I3 pivotally connected thereto so as to be free to rotate,

the receiver J being supported thereon. The

lever I and hence the receiver hook la are mounted at one side of the axis K about which the receiver and cylinder H move. This construction is shown in Fig. 4. It will be seen from this :figure that the said receiver hook is about 45 beyond the axis K. This construction insures the pulling outl of the lever l by the receiver in all its various p ositions so as to keep 4the Contact lever I2 in position to insure the proper circuit connections. The curve of the neck H1 is such that altheugh the receiver hoek is pivoted above the pivot about which the transmitter Iisrotated, it will still operate in all the various positions of the transmitter. The lever I is f elevated upon the removal of the receiver by means of the usual spring actingupon the contact lever I2.

It will be seen that by means of this construction the transmitter and receiver may be adjusted kto various positions and held therein, and they may be moved up against the wall to be out of the way when not in use, and may then be pulled out to the proper position with relation to the users mouth, their parts being so arranged that the device is self-adjusting in every particular. When, for example, the parts C or D are moved up or down thel part G is rocked so as to keep the cylinder H and the receiver in proper relation to the user, that is to say, to keep the lmouth ofthe transmitter pointing in the right direction. If, for example, the pieces C and D are moved downwardly and the cylinder H were to remain in the same relative position as shown at present in Fig. l, the mouth of the transmitter would then point down to too great an extent.. This is obviated by the piece Gr which is moved out at the lower end, that is, the end connected to the part D, thus lifting the cylinder H and the transmitter. It will be seen that by this means an automatic adjustment is secured. The spring lift makes this movement easy of accomplishment. The conductors L leading to the receiver are connected with suitable terminals Ifl at the end of the cylinder H so that the movement of the parts invno manner interferes with.

the electrical connections. The electrical connection to the cylinder I-I is also such as not to be interfered with by the movement of the parts.

I have described in detail a particular construction embodying my invention, but it is of course evident that the parts may be varied in many particulars, and'I therefore do not limit myself to the particular construction shown.

I claim:

1.l A telephone apparatus comprising an adjustable bracket, a cylindrical part pivotally connected therewith and provided with a curved neck, the pivot connecting said cylindrical part to the adjustable bracket vbeing in line with the center of the cylindrical part and at an angle to the axis of said cylindrical part, a transmitter rigidly connectedwith said neck, a pivoted lever connected with said neck so as to move therewith and provided with a circuit varying device, and a receiver hook pivotally connected with said lever.

2. A telephone apparatus comprising an adjustable bracket, ajcylindrical part pivotally connected therewith and provided with a curved neck, a transmitter rigidly connected with said neck, a lever pivotally connected with said cylindrical part and provided with a circuit varying device, and a receiver hook pivotally connected with said lever, said lever and receiver hook located at one side of the pivot about which said transmitter and cylindrical part move, the pivot -for said lever being exterior to said cylindrical part.

8. A telephone apparatus comprising an adjustable bracket, a cylindrical part pivotally connected therewith and provided with a curved neck, a transmitter rigidly connected with said neck, a lever pivotally connected with said cylindrical part andl provided with a circuit varying device, and a receiver hook pivotally connected with said lever, said lever and receiver hook located at one side of the pivot about which said transmitter and cylindrical part move, said cylindrical part provided with a removable side piece by means'o which the interior is exposed, and a signaling device located on said removable side piece.

4. A telephone apparatus comprising an adjustable bracket, a cylindrical part pivotally connected therewith and provided with a curved neck, a transmitter connected with said curved neck, a receiver hook and lever pivotally connected with said cylindrical part above the pivot about which it moves, the receiver hook and lever being pivotally connected together, the pivot for said lever being exterior to said cylindrical part.

`5.
